Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed January 3, 1905. Serial no. 239,314. I

' Be itknown that '1, JOHN YOUNG, of Syracuse, in the countyof'Onondaga, in the State ofNew York, have invented new and usefulImprovements in Dumping-Wagons, of which the following, taken inconnection with the. accompanying drawings, is a full, clear, and.

exact description.

This invention relates tofthe class of dumpdirection, while a dogengages the ratchet to prevent reverse movementof the ratchet when 7released from the-pawl. I v I i he object of the invention is toprovidesimple, durable, and efiicient means for throw- I ing the dog and pawlboth out of engagement in with the ratchet by the samelever'whichcarriestheaforesaid pawl, thus requiring only one lever for operating thewinchto lift the .floor to its closed position and for releasing thewinch to allow the said floor to drop toits open position; and to thatend the invention consists in the novel construction and combination ofthe winch operating and controlling de vices hereinafter described,andias illustrated in the accompanying drawings, in which;

Figure 1 is a side view of the body of a dumping-wagon embodying myinvention in" its normal condition. Fig. 2 is a plan view of the same. IFig. 3 is a longitudinal section on the line 3 3' in Fig. 2. Fig. 4 isfiliIfiJlSr verse section on the line 4 4 in Fig. '1. Fig. 5 is anenlarged vertical transverse section of the winch operating andcontrolling devices.

' Fig. 6 is a plan view of the'same'. Fig.7 is

a transverse section on the line 7 7 111 Fig.5; and Fig; 8 isa verticallongitudinal section of the body-of a dumpingfwagon, showing myinvention in position for dropping the .floor' ofsaid body. Similarletters of reference indicatecorre- .sponding parts. I

* represents the body of the. dumping- Wflgonp i Y B denotes the dropnew or bottomfof, said I body, which floor is'divided intotwo side sec-ftionshinged tothebody, as shown at aim, to

allow said sections to drop .into position to d scharge'the contents ofthe body.

Tothe under side of the floor-sections, ad

ja'cent to the meeting edges thereof, areattachedlongitudinal bars 6 b,which serve to stiffen said sections. To the end portions of these barsare attached brackets 0 0, to'which v are pivoted sheaves (Z d, on theunder sides of which run chains e (2, each of which. passes over'ahorizontalroller f, mounted in. bear-. lngsf f, attached to the exteriorof the rear end of thebody A; The rear end portions of. said chainspassfrom the roller f down to. the ends of the bars-.65 and are fastenedthereto. The front end portionsof the chains pass from the front sheavesd d upandover aroller g, pivotally supported on-the exterior Thechainsof the frontend of the. body A. V passthence to the winch C, upon whichthey 'arewound. Said winch is mounted in suitable bearings'attached toextensions A of the sidewallsof the body A. it represents a ratchetwhich isfastenedto the winch. I

A lever Lis pivotally connected to the 'winch'and has pivoted to it a.pawl a, which engages-jthe ratchet when the lever L isoperated to windthe chains 66 on the winch, and

thereby lift the floor-sections to close the bottom of the body A.

j represents the dog which engages the" of while thepawl is carriedto'aposition to ratchet to prevent retrograde movement there-' obtain a newhold on they ratchet. This dog the said dog to normally engage theratchet, I form the dog'with a depending weight Z,

"is pivoted to a bracket R. attached to the side d of the body extensionA. In order to cause I, 9

which is disposed to swing the dog jinto en- I gagement with theratchet. In order to throwthe saiddog and pawl out ofengagement by thesame lever Lwhich carries said pawl, I form the dog with anupwardly-extending armn andwith a head oonthe top of the frontv of thedog and attach to the lever L a V stud or roller 9, which is caused topress on theback of the free end of the .arm n by a I downward pressureapplied to the lever. Said pressure on the arm n throws the dog j out ofengagement with the ratchet. I Simultanes ously'with this movement ofthe dog the head othereof engages the under side of the pawl c' andlifts the same from thefratchet. -T he ratchet being thus released fromthe dog j and pawl allows the winch C to-yield to the v strain of thechains 6 e,which are thus unwound on the winch and caused to allow thefloorseotions B to drop to their open position .on the body A, as shownin Fig, 8 of the drawings.

In lifting the floor-sections to their closed position the lever isswung rearward from the position shown in Figs. 1, '2, and 5 of thedrawings, and in this movement therarm n and head 0 of the dog jare outof engagement with the stud or roller 7 and pawl 71, and thus the saiddog is allowed to assume itsnormal position for engaging the ratchet andprevent retrograde movement of the ratchet while released from thepawlz; in swinging the lever L forward to cause the pawl to. obtain anew hold on the ratchet-..

To carry the chains 6 e laterally from under the center of the body Aand shield said chains. when the floor-sections are dropped to dischargethe contents of the said body, I attach to the under side of saidfloor-sectionssu'itable brackets 25 2 disposedat intervals in the.length of the body A and-receiving the chains through them.

What I claim asmy inventionis 1. The combination, with the ratchet,lever and pawl pivotedtosaid lever, 'ofa dogdis-H posed to becomeinterposed between the pawl and ratchet by the movement of the lever andactuated-by said lever to throw dog from the ratchet and simultaneouslycause the dog to pry the pawloutof. engagement as set forth.

2.. The combination with the ratchet, lever and pawl pivoted to saidlever, of a pivoted dog disposed to become i'ntrpased betweentivelythelever and the pawl and therebythrow the dog and pawl both outof engagement by, the movement of the lever in one. direction.-

4. The combination, with the wagon-body havingdrop-floorsectionshingedto said body, a floor-lifting winch,'a ratchet attached to said winch,and a lever provided with a pawl for engaging the ratchet, of adogformed with 9. depending weight to hold the dog normally inengagement withthe ratchet, a forwardlyprojecting head on the dog and anupwardlyextending arm fixed tothe dog and disposed in front thereof, anda roller pivoted to the handle and in position to pressthe aforesaid armforward and thereby throw the dog out of engagement and cause the headthereof to hold the pawl from engagement asset forth.
